When United Airlines allegedly broke the guitar of the Canadian country and western singer Dave Carroll, he took revenge in a YouTube music video that became a huge hit this summer. The song, United Breaks Guitars, has been viewed nearly 5 million times on YouTube.

Carroll wrote the song after claiming United broke his Taylor guitar in 2008. The airline succumbed to pressure, offering to pay to repair the guitar as well as giving Carroll flight vouchers, but in another YouTube video he asked the airline to donate the money to charity. In that video he defends Ms Irlweg, the United Airline customer services worker who dealt with his case (and whose intransigence he pilloried in the first song), who had apparently become something of a hate figure for over-zealous viewers.

Now he's back with the second song of what he says will be a musical trilogy based on his experience. United Breaks Guitars Song 2 is a lament to Irlweg about what could have been, had she not been forced to adhere to United's policies. "United sees no need to make anything right, oh Ms Irlweg, we don't need to fight... We could be best buddies, but our friendship has been muddied," he sings.

The video shows Carroll, who usually performs with his brother Don as the band Sons of Maxwell, befriending a woman and enjoying a picnic and three-legged race.

On his personal website, Carroll says it was a "much bigger production" than the first. It was written in February and filmed behind a fire station in Waverley, Nova Scotia, on 5 August. Fans have been given no indication yet as to the release date of United: Song 3.
